Package emacs-common-proofgeneral

Proof General is a generic front-end for proof assistants (also known
as interactive theorem provers) based on Emacs.
Proof General allows one to edit and submit a proof script to a proof
assistant in an interactive manner:
- It tracks the goal state, and the script as it is submitted, and
allows for easy backtracking and block execution.
- It adds toolbars and menus to Emacs for easy access to proof
assistant features.
- It integrates with Emacs Unicode support for some provers to provide
output using proper mathematical symbols.
- It includes utilities for generating Emacs tags for proof scripts,
allowing for easy navigation.
Proof General supports a number of different proof assistants
(Isabelle, Coq, PhoX, and LEGO to name a few) and is designed to be
easily extendable to work with others.
